2 Device description
Infographic Article no. Description
AX2090-ND80 The external mains chokes of the AX2090-ND80
series are made for minimize mains perturbation and
reduce reactive power components. In addition, the
mains chokes reduce charging currents in the DC link
capacitor and contribute to an improvement of the cos
(phi) at. All mains chokes of the series AX2090-ND80-
xxxx are cUL and CSA approval.
Intended use
Mains choke AX2090-ND808 Version: 1.0
3 Intended use
The mains chokes from the AX2090-ND80-xxxx series are intended exclusively for use directly on a supply
module from the AX86xx series. They are installed together with the AX86xx supply module on a multi-axis
servo system as components in control cabinets of electrical systems and machinery and may only be
operated there.
WARNING
Nature and source of the danger
Basically, electronic devices are not fail-safe. The machine manufacturer is responsible for
ensuring that the connected motors and the machine are brought into a safe state in the
event of a fault in the drive system.
Improper use
The AX2090-ND80-xxxx mains chokes are not suitable for use in the following areas:
• in ATEX zones without a suitable housing
• in areas with aggressive environments (e.g. aggressive gases or chemicals)
The relevant standards and directives for EMC interference emissions must be complied with in residential
areas. The brake resistors may only be installed in housings and control cabinets with appropriate shielding
attenuation.
Special safety notes on brake resistors
Mains choke AX2090-ND80 9Version: 1.0
4 Special safety notes on brake resistors
The responsible staff must ensure that the application or use of the products described satisfy all the
requirements for safety, including all the relevant laws, regulations and guidelines.
DANGER
Danger to life due to high voltage on the DC link capacitors of the servo drive
AX8000!
The DC link capacitors RB+ and RB- and the test contacts DC+ and DC- on the
supply, axis and option modules can carry life-threatening voltages of
≥ 875 V
DC
.
Take the following measures to avert danger:
• After disconnecting the servo drive from the mains supply, wait until the voltage has
fallen below 50 V
DC
. Only then is it safe to work.
• Measure the voltage on the test contacts properly.
• Secure the work area properly and wear the PPE.
WARNING
Caution - Risk of injury through hot surfaces!
The temperature of the mains choke housing surface may reach over 100 °C. Please en-
sure that the housing has cooled down below 40 °C before touching it.
UL- recognized component
The mains chokes from the AX2090-ND80 series are certified according to applicable UL
and CSA safety requirements. They may therefore be used in products, plants or systems
bearing the UL-Listing test mark.

WARNING
Caution - Risk of injury through electric shock!
De-energize all electrical components (servo drive, control cabinet etc.) before commenc-
ing the installation or deinstallation of the mains choke.
WARNING
Caution - risk of injury through high voltages!
Mains chokes contain components that can store electrical charge. Wait 10 minutes after
disconnecting the mains chokes and measure the voltage on conductors L1 to L3. You can
ensure safe working by letting the voltage drop below 50 V.
CAUTION
Beware of improper earthing!
Ensure proper earthing during installation of the mains chokes. The installation should take
place on a mounting plate (chromated / galvanized) suitable for earthing.
6.1 Circuit diagram and installing
Assembly sequence:
• Position the mains choke on the mounting
surface.
• Mark the positions of the thread holes on the
mounting surface.
• Centre and drill the thread holes. Then cut the
threads in the holes.
• Secure the mains choke on the mounting
surface with suitable screws.
Connection:
• Connect the protective conductor connection of
the mains choke with the PE rail.
• Connect the connecting cable of the mains
choke to the appropriate terminals of the servo
drive.
• Connect the mains choke to the supply
network.
